IMPROVEMENT IN BOLT-WORKS FOR DOORS Specification forming part of Letters Patent No. 128,816, dated July 9, 1872.

Specification describing certain Improve ments in the Bolt-Work of Safe and Vault Doors, invented by JAMES SARGENT, of Rochester, in the county of Monroe and State of New York.

Nature of Invention.

General Description.

In the drawing, Figure 1 is a horizontal section of the door and jamb of a safe; Fig. 2, a perspective view of the door thrown open; Fig. 3, a perspective view of the wing or bolt of the door, the operating-cam, and the lockbolt; Fig. 4 an elevation, showing a fragment of the safe and exhibiting more particularly the seat or flange of the jamb.

Arepresentsaportion of the body of the safe B, the door; and O, the lock, which is located within the door and operated by the knob and spindle D, as usual. I form in thefront edge of the door a cavity or socket, which receives a wing, E, extending up and down from end to end, or to any desired length, which forms the bolt-work, resting flush in the door when unlocked, so that the door will swing open, but projecting when thrown out or locked so as to engage with a flange, G, of the jamb, and thereby prevent opening. It is preferably hinged or jointed at the rear edge a, being held by screws or pivots at top and bottom, or by hinges intermediately and resting in a corresponding half round cavity or seat, which makes a close joint; but, if desired, the joint may be dispensed with, and the whole wing moved out and in bodily. It will be seen that the open or swinging end is free to be thrown out or in, and that when thrown out, as in Fig. 1, the flange G serves as a stop, and the safe cannot be then opened. If desired, the wings E may be applied on the four edges of the door, and may be so connected as to be operated simultaneously by the action of one spindle; but in fire-proof safes the single wing on the front edge is usually suflicient. H is a collar, made fast to the spindle I. This collar has two cams, b c, which stand at right angles or nearly so to each other. The cam b connects with the wing E by means of a crankpin, d, which works in a slot, f, of a lug, g, that forms a part of the wing. The length of the slot is sufficient to allow the rise and fall of the pin in the turning of the cam. The other cam 0 stands upright against the turning lock-bolt K, which holds it in position so that it cannot turn except when said lock-bolt is retracted. When in this condition, as shown in Fig. 1, the wing E is thrown out to engage with the flange G, and the end of cam 12 rests against the body of the wing, and serves as a stay to it, so that no strain comes upon pin d; but when the lock-bolt is retracted then cam a can be turned down and the cam b be turned up, drawing the wing with it into its seat or cavity in the edgeof the door. The locking and unlocking of the wing with the jamb is therefore alwayspositive in action. And, when locked, since the two cams b 0 are firmly braced between the wing and the lock-bolt, there can be no possibility'of the opening of the safe by any power applied to the spindle- The lock bolt may be either circular or segmental, as shown in the drawing, and may release the cam by simply turning upward, or it may be the ordinary sliding-lock-bolt in common use; and the lock-bolt instead of being located close up to the cam, as shown, may be located at a distance, and a sliding bar or oth or device may be used as a connection between it and the cam 0.

As the heavy door of a safe or vault is liable to sag more or less, and therefore disarrange the joint between the edge of the wing and its stop and cause it to bind, I insert through the flange G a series of screws, kJc, as shown in Figs. 1 and 4, or employ some equivalent arrangement which can be set in or out as necessity may require, to allow proper freedom to the door. Corresponding sockets m may be made in the plate of the door to en able the door to shut over the heads of the screws when the latter are drawn back so as to project outward. These screws are set in so as to form the stop to the edge of the wing, and if sagging occurs so that the door does not shut perfectly-tight the screws are turned out or in to compensate or adjust for the difference in closing. By this means the joint may always be kept close and no looseness can occur. This arrangementismore particularly adapted to fire-proof safes and vaults,though it may be used to advantage on burglar-proof work.

I am aware that in burglar-proof safes a bolt-work has been formed of plates attached on the outside of the inner plate or face of the door, and made to slide over the joints by means of a system of levers, pinions, &c. Such is not the equivalent of my invention.
